REVERSING MECHANISM.

SPECIFICATIONfOrming' part of Letters Patent No. 759,875, dated May 17, 1904.

Application filed August 6, 1903'.

To all whmn it may concern:

Be it known that I, HERMAN GANsEnT, a citizen of the United States, residing at the city of New York, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Reversing Mechanism, of which the following is a specification.

The object of my invention is to provide a new and improved reversible clutch which is simple in construction, strong, durable, and can readily be adjusted to rotate in either direction by means of a singleshiftingdever, does not strain the hearings or supporting brackets or hangers, and is not apt to get out of order.

In the accompanying drawings, in which like letters of reference indicate like parts in all the figures, Figure l is a side elevation of my improved reversible clutch, parts being broken out and others shown in section. Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1, parts being broken out. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is a top View of the split friction-clutch ring.

The shaft A is mounted in two hangers B, which are secured to the ceiling or other overhead support, which hangers have suitable bearings, and in them the shaftA is mounted loosely. A sleeve C is mounted loosely on the shaftAand is provided at one end with atransverse piece or arm I) or, in other words, with a cross-piece projecting diametrically in opposite directions. On one end of this cross-piece a cog-wheel E is mounted to turn, and the other end. is preferably enlarged, so as to counterbalance this cog-wheel. The cog-wheel E engages a cog-wheel F, concentric with the shaft A and fixed on one end of a sleeve Gr, mounted loosely on the shaft A and provided with a belt-pulley H, over which the driven belt passesthat is, the belt for operating the machinery driven from this clutch-pulley. A disk J, provided with a flange K, forms the pulley for the driving-belt, and on the inner surface of said flange an annular rack L is formed, which is engaged by the cog-wheel E. This disk J is loosely mounted on the sleeve C and rests against the cross-piece D. A ring M, having its outer surface beveled downward Serial No. 168,443. (No model.)

and toward the shaft at both sides, is mounted to slide on the sleeve O, and this ring M is surrounded by a ring N, said ring N being attached to a shifting lever O and suitably pivoted overheador in any other suitable manner, so that by means of said lever-O the ring M can be moved toward and from the disk J. The bearing P at that end of the sleeve C opposite the'one having the cross-piece D is enlarged to form an abutment P, having a socket R, and a similar socket R is formed in the outer side of the disk J around the sleeve C. Each of these sockets contains an expansible or split ring S, having a flange S, which when the ring is spread binds on the side walls of the socket, and this ring also has a central hub S At the top and bottom the ring is split. At

the sides of the bottom slot lugs S are cast integral with the ring, and through these lugs a clamping-screw S is passed. The sleeve C is surrounded by the hub, and by drawing up the screw S the ring is clamped firmly on the sleeve C without interfering with the slight expansible movement necessary for the flange S. A cam-pin V is mounted to turn axially in the upper slot in the split ring S :and is provided with an arm T, provided at its free end with an outward-projecting finger or pin T. A spring T acting on the arm R, serves to pull the same in such direction that the longer axis of the cam-piece V is parallel with the sides of the slot. When the arm T is pressed laterallythat is, toward the face of the ring the cam V is moved axially and by acting on the sides of the slot in which it is located expands the ring and. causes it to bind in the socket.

1f the lever O is shifted to the right, Fig. 1, the cam-ring or beveled ring M with its left bevel engages the pin T on the arm T of the friction-clutch in the socket R in the disk J, whereby the clutch-ring S in the socket R in the disk J is spread and caused to bind in said socket.

The driving-belt of the pulley K rotates the same, and as the disk J is locked to the sleeve by means of the right-hand friction-clutch, as

described above, it follows that the cross-piece 1) rotates with the disk J, and thus no rotative movement of the wheel E in relation to the flange K takes placethat is, no rotation of the said wheel E on its pivot. The wheel E is thus practically fixed in relation to the crosspiece D and flange K. As this wheel cannot rotate the engaging wheel F on the sleeve Gr, carrying the belt-pulley H for the driven belt, it follows that the sleeve G and pulley H must participate in the rotation of the sleeve O and disk J that is to say, the pulleys K and H are rotated in the same direction. If, on the other hand, the lever O is moved to the left so that the left-hand bevel of the ring M engages the pin T of the friction clutch mechanism of the socket R in the enlargement or abutment I of the bearing P, the friction-clutch in this enlargement or abutment is spread, whereby the sleeve 0 is locked firmly tosaid abutment and cannot rotate. The disk J is now no longer held on the sleeve C, but is loose on the same. The driving-belt on the pulley K rotates the disk J on the sleeve C, which is now locked to the abutment P, as stated above, and the annular rack formed on the inner side'of the flange K, engaging the wheel E on the cross-piece D, rotates said cog-wheel E, and the latter in turn rotates the cog-wheel F on the sleeve G, which carries the pulley H for the driven belt, which pulley H for the driven belt is now rotated in the reverse direction of the pulley K. The sleeve G may be fixed on the shaft A or mounted loosely on the same. If this sleeve G is mounted loosely on the shaft A, the shaft may be fixed; but ifthe sleeve G is fixed on the shaft the shaft must necessarily be mounted to turn.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a reversible clutch the combination with a shaft, of a sleeve on the same, a beltpulley on said sleeve, and a cog-wheel fixed on said sleeve, of an additional sleeve mounted on said shaft, and having across-piece, a cogwheel on said cross-piece engaging the cogwheel on the first-mentioned sleeve, a disk mounted to turnon the sleeve provided with the cross-piece, which disk has a flange forming a belt-pulley, acircular rack formed on the inner face of said flange and means for locking the said disk to the sleeve on which it is mounted and means for locking said sleeve to prevent its rotation, substantially as set forth.

2. In a reversible clutch, the combination with a shaft, of a sleeve on the same, a beltpulley on said sleeve, a cog-wheel on said sleeve, an additional sleeve on the shaft, which additional sleeve is provided with a cross-piece,

a cog-wheel mounted on said cross-piece and engaging the cog-wheel of the first-mentioned sleeve, a disk mounted to turn on the sleeve provided with the cross-piece having a flange forming a belt-pulley, a circular rack formed on the inner side of said flange, and engaging the cog-wheel on the cross-piece above mentioned, arrabutment formed on one bearing of the supporting-shaft and means for looking the above-mentioned flanged disk on the sleeve on which it is mounted and means for locking the said sleeve in fixed position to said abutment, substantially as set forth.

4:. In a reversible clutch, the combination with a shaft, of a sleeve on the same, a pulley on said sleeve, a cog-wheel on said sleeve, an additional sleeve mounted on the shaft and provided with a cross-piece, a cog-wheel on said cross-piece engaging the cog-wheel on the first-mentioned sleeve, a disk mounted to turn on the sleeve provided with a cross-piece, which disk has a flange forming a belt-pulley, a circular rack formed on the inner side of said flange and engaging the cog-wheel on the cross-piece, a fixed abutment at one end of the shaft, a clutch-rin g in said abutment, a clutchring in the disk on the sleeve provided with a cross-piece, a shifting piece on the sleeve provided with the cross-piece, for operating the clutch devices in the abutment and in the disk and locking said sleeve either to the abutment or to the disk, substantially as set forth.
